    Buy the book. Read Part I for the love story. Skim Part II for the chemistry. Keep it on your shelf as a piece of history. And whatever you do—stay safe, stay legal, and stay curious.

    If you’ve landed here searching for a PIHKAL PDF, you’re likely curious about one of the most famous—and infamous—books in the world of psychopharmacology.

    The Shulgins were brilliant, but they were also professional chemists working with sophisticated equipment, fume hoods, and analytical standards. Many of the compounds in PIHKAL are Schedule I controlled substances. Attempting to make them is incredibly dangerous (toxic gases, explosions, fires) and illegal in nearly every country.

    Written by the legendary chemist Alexander “Sasha” Shulgin and his wife Ann Shulgin, PIHKAL: A Chemical Love Story is more than just a recipe book. It’s a 1,000-page masterpiece split into two very different parts: a fictionalized autobiography of a love story, and a detailed scientific appendix of 179 psychoactive compounds.
